The Marlins recalled Wall from Triple-A Jacksonville on Sunday.
Wall will take the vacant spot on the 26-man roster that was left by Jazz Chisholm, who was traded to the Yankees on Saturday. Wall was claimed off waivers by Miami on Thursday after Atlanta designated him for assignment three days earlier. He has a slash line of .241/.313/.241 with three stolen bases, three runs scored and one RBI across 32 major-league plate appearances this season.
